HOT-WATER AND STEAM RADIATOR.

SPECIFICATION forming pari; of Letters Patent No. 385,679, dated July 3, 1888.

Application tiled July 5.18%?. Serial No. 243.364. (No model.)

To all whom t may concern.-

Be it known that I, CHAILEs W. NEWTON, a citizen of the United States, residing at Baltimore,in the State of Maryland,h ave in vented certain new and useful Improvements in Hot- Tater and Steam Radiators, of which the following is a specification.

My invention relates to improvements in the construction of radiators for heating by the use of steam or hot water.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the radiator. Fig. 2 show s the construction that would be seen on a horizontal section of the radiator. Fig. 3 shows construction that would be seen on a longitudinal vertical section of the radia tor. Fig. 4 is a vertical elevation showing a portion ofthe case or snell end. Fig. 5 isa top view of a portion of the chest end. Fig. G is au end view showing a portion, being a lower corner, of the chest end, showing the manner of fastening the leg thereto.

The end A designates the chest, which is at one end and comprises two broad walls, Z), counected at top, bottom, and sides by narrow walls c, and forming a chamber, A, for steam or hot water, into one broad side of which the horizontal pipes d d enter. It will be seen the walls ofthe chest or chamber A are made in square panel-sections, which are divided or made distinct by the exterior grooves, j', which extend horizontally and vertically. On the interior and directly opposite the exterior grooves the wall has ribs f', which also eX- tend horizontally and vertically, like the grooves. This special construction has been contrived to afford certain advantages, to wit: First, the metal of the panels e may be thin and light, and the interior ribs will afford to the broad walls the desired stiffness and strength; second, by thus making the entire walls of the chestin comparatively small square panelsections I am able to make the patterns from which the walls are molded in separate sections or parts, the edges or lilies ofjoinder of which parts will be at the center of thesaid exterior grooves, f. The necessity of an entire different pattern for each size and shape of chest is thereby obviated, anda dozen or more different sizes may be made by simply combining in then1olding-iiask a sufficient number of separate sections of the pattern to producel the article wanted. The case or shell G is at the opposite end, and supports the pipes d and incloses the return-couplings 7L. The case or sliell'comprises an outer wall, b, and top, bottom, and side walls, c'. This end is made of square panel-sections of the same size and for the same purpose as described for the chest end.

The top, side, and bottom walls, c', have scallops or rounded notches i, into which the `return-couplings h tit, and at the inner side of each notch is a lng,'k. Each ofthese couplings has a rim-flange, h, around its two ends. The face of this flange is the part which bears against the notches z'. The back edge, k', of the tlange rests against the lugs la, as shown in Figs. 2 and 4, and thereby the return-couplings h are prevented from moving backward into the case or shell G. A cross-bar or spider, Z, having four arms is employed to stay the adjoining couplings and support the pipes in properrclativeposition. Theendsofthearms of this spider are concaved to fit the pipes d d', and they have position against the front edge, l', ofthe coupling-flange. These spiders are tapped and screw-threaded at the center, and the outer wall, b', has bolt-holes m, as many as may be deemed necessary; but ordinarily fourare sufficient. A bolt,a,is passed through the said hole m in the wall and into the spider, as seen in Figs. 2 and 3, and thereby the pipes and case or shell G are confined together. 1t will be seen the fixed lugs k, which take on the back edge of the eoupling-iiange, and the arms of the spider Z, which take on the front edge thereof, with the bolts a, connecting the wall and spiders, secure the pipes and case very efectually, and at the same time enable them to be readily detached.

A special construction is provided for fasten ing the legs O to the radiator. The lower cor ner of the chest A (see Fig. 3) has a swellbeaded edge, p, on two opposite sides, and on the bottom between the two edges p has a lug, g, with a bolt-hole. The leg O at its top has a slide-groove, r, at cach of two opposite sides, whereby the leg may slide onto the said two beaded edges 1J. A bolt, s, passes through the leg and into the bottom lug, q, and thereby retains the leg.

IOC

In supplying the radiator, water first enters the bottom pipe, t, and rises in the radiatorchest A and pipes d d', and the air therein is forced out or expelled at the top pipe, u.

Thepanel-seetions are here shown square; but they may be of various other shapes and effect the desired end. By my construction ot' the ease or shell end G, and combining therewith so as to inelose the return bends or couplings h of the circulating-pipes, both ends of the radiator have the same appearance.

Vhen the radiator is full of water and the water heated, the circulation in the radiator is as follows: The hot water will enter at the pipe u and ow through the irst series ofthe upper pipes, d, the return-couplings 7L, and back th rough the lower pipes, d, into the chest end A, thence through the next lower series of pipes d and d/ into the chest end, and so on until the water passes out of the pipe t to return to the boiler.

Having described my invention, l claim and desire to secure by Letters Patent of the United Statesl. The combination, iu a radiator, of the horizontal circulating-pipes d d', the returncouplings 71., uniting the ends of said pipes, the supporting case or shell inclosing the returncouplings, the cross-shaped spider having its with the return-couplings, and the bolt n, connecting the case-wall and spider, substantially as specified.

3. The eoxnbinatiou,iu a radiator, ofa chest, A, formed of panel-sections e, and having a swell edge, p, on two opposite sides and botl ton1,and provided with a downward-projecting lug, q, having a suitable bolt-hole, a leg, provided at its top with a slide-groove, r, to engage the swell edges, and a bolt, s, passed through the leg and into the said downwardprojecting lug, substantially as specified,

In testimony whereof Iax my signature in the presence of two witnesses.
